Rod and piston seals

Powerbands are manufactured from a highly engineered blend of premium nylon, glass fiber, and PTFE, to serve as a high strength wear-ring for all cylinder applications, including those with minimal lubrication. They are fully machined with cross-section tolerances of only ±0.001 in., chamfered corners, and scarf or angle-cut end gaps. These features improve alignment and concentric operation of cylinder rods and pistons, better accommodate cylinder housing grooves, further improving piston and rod alignment, and reduce the loss of bearing support that may occur during cylinder side-loading.
